SPECIFICATION forming part of Letters Patent No. 652,914, dated July 3, 1900.

Application filed February 8,1900. Serial No. 4,519. on model.)

To all whom it may concern.-

Be it known that I, FRANKLIN CLARKE DAVIS, a citizen of the United States, residing at Toccoa, in the county of- Habersham and State of Georgia, have invented a new and useful Cotton-Planter and Fertilizer-Distributer Attachment, of which the following is a tachment adapted to be attached to and to operate in conjunction with a shovel or other suitable form of plow, which shall be cheap, of simple construction, and adapted to operate efficiently for the purpose of planting cotton-seeds and distributing fertilizers in connection with the planting thereof and separately.

In the accompanying drawings, Figure 1 is perspective View of a cotton-planter and fertilizer-distributer attachment embodying my improvements, showing the same in operative relation to a furrow opening and covering plow. Fig. 2 is a vertical sectional view of the same detached from the plow. Fig. 3 is a similar view on a plane at right angles to Fig. 2. Fig. 4 is a detail sectional View, on a somewhat-enlarged scale, of a portion of the bottom plate, showing the discharge-opening formed therein, the vertically-movable cutoff plate to regulate the discharge of seeds and fertilizer from the seedbox, and also showing the guard which bears against the outer side of the cut-off plate. Fig. 5 is a detail view of the cut-off plate;

In the embodiment of my invention I employ a combined fertilizer and seed box 1, which is preferably of the form here shown and of asuitable size to adapt the same to be readily attached to and detached from a cultivating or other suitable form of plow, as shown in Fig. 1, for which purpose I'provide the said box 1 with suitable hooks 2 atitsupper end on opposite sides to engage the round 3, connecting the plow-handles, and I further provide one or more metallic strap-links 4 near the lower end of the box 1 on the front side thereof, adapted to be bolted to the plow.- beam, as at 5, hence disposing the box 1 in rear of the plowbeam and behind the plowhandles.

The lower end of the box-1 is closed by a bottom plate 6, the sides of which are preferably downwardly inclined, as at 7. Bearings are formed at the lower sides of the box,

as at 9, in which bearings are journaled a transversely-disposed operating-shaft 10, provided with a feed-worm 11, the latter being arranged above and in proximity to the depressed transverse semicylindrical channel 12,form ed in the bottom plate 6. A dischargeopening 13, formed in the bottom plate, is at one end of the feed-worm adapted for the discharge of the cotton-seed and fertilizer. The cotton-seed and fertilizer may be commingled before introducing them to the seedbox or they may be used separately, the machine being adapted for discharging either cottonseed or fertilizer, or both, as willbe understood. An adjustable cut-off plate 14 is disposed transversely with relation to the bottom plate 6, is located across the dischargeopening thereof, and has a discharge-opening 8 formed in its upper side, in which dis- 8o charge-opening operates the shaft 10. Adj Listing-bolts 29 depend from the inclined upper portions of the bottom plate 6 andoperate in lugs or ears 30, formed at the ends of the cut-off plate, and by turning the adjusting-nuts 31 on said bolts the cut-off plate may be adjusted vertically to enlarge or reduce the size of the discharge-opening therein, as may be required, so as to control the discharge of the seed and fertilizer by the feed-worm. go On the outer side of the cut-ofi plate is a guard 28, which is secured transversely on the bottom plate 6 and bears against the said cut-01f plate and serves to brace the same and form a guide therefor and prevent the said cut-off 5 plate from being laterally displaced by the action of the feed-worm on the-seeds and fertilizer. V

On one end of the shaft 10 is fixed a wheel 16,- which operates by frictional contact with the earth and serves to impart rotary motion to the shaft and feed-Worm. Said shaft is provided at the end opposite the wheel 16 with a crank 17. An oscillating stirrer 18 is disposed transversely in the box 1 near the lower side thereof and is journaled therein, as at 19, said stirrer being of substantially U shape and provided with an exterior crankarm 20. Said crank-arm is connected with the crank 17 of the operating-shaft by a link 21, and it follows that when said shaft is rotated oscillating motion is imparted to the stirrer 18, which serves to prevent the mass of fertilizer and cotton-seeds in the box from packing therein and to adapt the same to be discharged regularly through the dischargeopening by the feed-worm.

As shown in Fig. 1, the plow is provided with a suitable furrow opening shovel or share, as at 22, and arms 23, which diverge rearwardly from the plow-beam and are disposed on opposite sides of the box 1, are pivoted to the plow-beam by a bolt 24. Said arms are provided with forward extensions beyond their pivots which bear on the sides of the plow-beam, and at their front ends have a series of adjusting-openings 25, which adapt them to be adjusted vertically and secured at any desired adjustment by a bolt 26, which passes through the plow-beam and is adapted to be passed through appropriate adjusting-openings. The arms 23 constitute plowstocks and are provided with suitable coverin g shovels or shares 27, which are adapted to cover the furrow made by the shovel or share 22 after the seeds and fertilizer have been deposited in said furrow by my improved attachment hereinbefore described.

Having thus described my invention, I claim- 1. A planting attachment for plows, comprising a seedbox adapted for attachment to the rear side of a plow, in combination with a shaft journaled in said seedbox and having a feed worm, a crank, and an operatingwheel, the latter being adapted for rotation by contact with the ground as the plow advances, an oscillating stirrer in said seedbox and having an exterior crank-arm, and a link connecting said crank-arm to the crank of the wheel-shaft, substantially as described.

2. In a planter, the seedbox having the bottom plate forming a channel, said channel having a transversely-disposed dischargeopening near one end thereof, a verticallyadjustable cut-01f plate disposed in the said opening, said cut-0E plate having a dischargeopening in its upper side and means to adjust said cut-ofi plate vertically, in combination with a shaft journaled in bearings with which the box is provided, said shaft being disposed in said channel of said bottom plate and havinga feed-worm therein, and extendin g through the discharge-opening-in the upper side of the cut-off plate and means to rotate said shaft, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

FRANKLIN CLARKE DAVIS.
